Description
The study of the Higgs boson properties is one of the main tasks of contemporary high-energy physics.
Among Higgs properties, its interaction with gluons is interesting since it can be facilitated by yet unknown elementary particles.
One of the major sources of uncertainty in the theoretical description of $ggH$ coupling originates from mixed QCD-electroweak contributions. The NLO QCD corrections to these contributions were evaluated few years ago in the approximation where electroweak boson masses were considered to be significantly larger than the mass of the Higgs boson and it is desirable to compute those corrections for physical masses of gauge bosons and Higgs boson.
In this talk, I will present a major step towards this goal and describe the analytic evaluation of NLO mixed QCD-EW three-loop virtual corrections to $gg \to H$.
